I been considering that also, in-addition to the co2 bags...Because I read that awesome to rid any pest, which I happen be dealing with this grow, first grow in I can't remember how long... But I know why, them damn smart pots... I forgot why I stopped using them, I was quickly reminded...but the problem with sulfur is my led says " NOT TO USE SULFUR " so am gonna have to ask, if I can or not. I hope your led won;t have same issue? am not sure why it says that, but when I opened box that was made pretty clear...
